Due to the recent rise of cardboard raw materials, the carton price has been quoted on the same day, thank the new and old households for their understanding and support

The layout expression of the carton is as follows: face paper name, component tile paper: tile paper strength, component, corrugated core paper: tile paper strength, component inside paper: paper name, component。

Example: Face paper cattle pickup 300g high watt 180g (AB Leng) core paper 180g Puwari paper 280g box board paper。

Corrugated box

Pricing formula: carton price (Yuan) = price per square meter of corrugated cardboard factory (Yuan /m2) × box open area (m2)

I. Accounting of the price per square meter of corrugated cardboard factory

1, the composition of corrugated cardboard

1) Definition and characteristics of corrugated type: according to GBT66544-1999 specifications, UV corrugated duty is divided into four types: A, C, B and E。

The height of the A-type is 405-5mm, and the number of inner creases per 300mm length unit is 32-36;

The height of the C-band is 3.5-4mm,300mm length unit inner number 36-40;

The height of the B type is 2.5-3mm,300mm length unit inner corrugated number 48-52;

The height of the E pattern is 1.1-2mm, 300mm length unit inner number 92-100。Carton price calculation carton factory calculation basic formula

The corrugated type of A is high and wide, so it is called the big corrugated type。The flat pressure function of the A-box is worse than that of the B and C box, but its straight pressure function is higher。Therefore, it is more suitable for the manufacture of cartons containing non-pressure items, and the use of comparison is common。The corrugated height and the number of corrugated boxes per unit length, as well as its function, are between A and B corrugated boxes, which are also known as fine corrugated boxes, and are suitable for holding ordinary items。The corrugated B type is low and dense, so the straight pressure resistance function is poor, but the flat pressure resistance function is high, so the B type paper is suitable for bottled bottled

等。E-corrugated cardboard corrugated is short and fine, so it is also called micro-corrugated type。The E-shaped paperboard has the characteristics of light weight, good buffering function and good plane compressive strength, which is conducive to printing directly。A, C, B these three types of corrugated cardboard, can also be combined into double corrugated and three-corrugated cardboard, so that the strength of the carton has been greatly improved。Cigarettes, glass containers and other non-pressure goods, most of the use of pressure resistance, impact resistance of the strong multi-layer layout of corrugated carton packaging。

2) The composition of corrugated cardboard

Corrugated board is divided into three layers of corrugated board, five layers of corrugated board and seven layers of corrugated board。The layout of the three-layer corrugated box is composed of a sheet of corrugated paper on both sides and a sheet of face paper。The five-layer corrugated box should be used for the lighter and easily broken contents of a single package;Five-layer corrugated box, also known as double corrugated box, used to be referred to as three yellow two tiles。The layout of the five-layer corrugated box is made of face paper, inner paper, two core paper and two sheets of corrugated paper. The combination of corrugated boxes is usually AB type (this type of pharmaceutical packaging is the most common), AC type, BC type, AE type or BE type。The seven-layer corrugated box consists of three layers of corrugated box board paper (to be used for the packaging of heavy goods, such as motorcycles, etc.);Composition: It is made of facial paper, corrugated paper, core paper, corrugated paper, core paper, corrugated paper and inner paper。The combination of corrugated type is usually selected BAB, BAA, CAC or BAC.

2, the unit of measurement of corrugated cardboard

1) Usually when the carton factory buys the face paper, inner paper, core paper and corrugated base paper, the price is calculated by ton。That is, how many yuan per ton of various face paper, inner paper, core paper, corrugated base paper, its unit indicates "yuan/ton", and it is necessary to replace "yuan/kg" when calculating.。If the purchase price is 5200 yuan ton, it is 5200 yuan /1000kg=5 according to the kilogram.20 yuan kg。Usually the weight of the paper is usually grams，In practice, it should be the number of grams per square meter, that is, the weight of various face paper, inner paper, core paper and corrugated base paper is represented by "grams /m2"，For accounting, it is necessary to unify the purchase of 300 grams of kraft paper，This is 300/gm2 kraft paper，Now convert "300g /m2" to (300/1000)kgm2"，则得0.3kg/m2。

3) Determine the coefficient of corrugated base paper manufacturing corrugated paper. The shortening ratio of corrugated base paper in the direction of paper length due to corrugated pressure is called the compression ratio coefficient。The reason is that the production talent and management level of each factory directly affect the yield of corrugated paper, but the packaging industry usually acquiesces in the following coefficients;

The compression ratio coefficient of A tube is 1.59，即1.59 meters of corrugated paper is 1 meter long after being corrugated。

The compression ratio coefficient of B tube is 1.36，即1.36 meters of corrugated paper is 1 meter long after being corrugated。

The compression ratio coefficient of C tube is 1.50，即1.50 meters of corrugated paper is 1 meter long after being corrugated。

The compression ratio coefficient of E tube is 1.27，即1.27 meters of corrugated paper is 1 meter long after being corrugated。

3, corrugated boxes of various paper per square meter of paper price accounting

(1) Algorithm of face paper, inner paper and core paper

例：进价4800元吨的面层纸为350克/m2，其每平方价应为；  （4800/1000）X(350/1000） =4.8X0.35 =1.68 (RMB/m2)

(2) Corrugated paper algorithm

Example: The purchase price of 1800 yuan tons of high-strength watts is 180 grams /m2, and its price per square meter should be: (1800/1000) X(180/1000) X1.59 =1.8X0.18X1.59 =0.516 (RMB/m2)

4. Accounting of the cost per square meter of corrugated cardboard raw materials

Existing customers to manufacture five-layer corrugated boxes, need to choose the face paper for 300g high watt 180g (AB corrugated) core paper 180g Puwari paper 280g tea board paper, test calculation of box board paper per square meter

Existing customers want to manufacture five-layer corrugated boxes, need to choose the face paper for 300 grams of high watt 180 grams (AB corrugated) core paper 180 grams of Puwari paper 280 grams of tea board paper, test the cost per square meter of box board paper quotation。

List accounting:

Paper, purchase price (yuan/ton) layer coefficient calculation type (yuan/per square meter)

Tissue cattle pickup 300 grams, 5200 yuan/ton, 1 (300/1000) (5200/1000) X 1 X1X1 = 1.56

High strength tile paper 180g, 2250 yuan/ton, 2 (1.56+1.39) (180/1000)X(2250/1000) x 2x2.95  =2.39

Core paper 180 grams, 1700 yuan/ton, 1 (180/1000) (1700/1000) X 1 X1X1 = 0.306

In paper tea board paper 280 grams, 2500 yuan/ton, 1 X1X1 (2500/1000) (280/1000) 1 X = 0.70 Sum (yuan per square meter) =4.96

Carton price calculation basic formula of carton factory price calculation 5. The factors and coefficients of corrugated cardboard factory price calculation

The ex-factory price of the carton shall include the sum of the carton material cost and other amortized expenses。Other expenses payable include auxiliary materials (adhesives, inks, flat wires, power), equipment depreciation, workers' wages, taxes, etc.

In the carton ex-factory price, usually the carton material cost accounts for 0.5～0.7, other amortized expenses accounted for 0.5～0.3, usually the manufacturer value is the carton material cost accounted for 0.65, other amortized expenses accounted for 0.35。The simple accounting is to choose half and half of the quantity is 0.The coefficient of 5 is greatly estimated。

6, the factory price of corrugated cardboard

Box board paper factory price = box board paper raw materials per square meter cost price 0.65 roots according to Article 4 "Total (yuan/per square meter) =4.96 "can calculate that the ex-factory price of box board paper should be: the ex-factory price of box board paper =4.96/0.65=7.63 yuan square meter

Two, carton area accounting

1) The open side of the carton is divided into a LCL containing a single piece on the side of four boxes and two LCL containing a single piece on the side of two boxes。

2) Calculation formula of carton area

Three layer box cardboard area (㎡) = (length + width +7) X2X (width + height +2) /10000。 Five-layer box cardboard area (㎡) = (length + width +8) X2X (width + height +3) /10000。  (Length, width and height are the inner diameter of the carton, unit centimeter, suitable for 0201 box type, outer diameter for inner diameter: five layers of length and relief 1, high minus 2, three layers of length and relief 0.5, high minus 1, later accounting) face paper, inside paper square meter unit price = the company's raw paper sold tons of price gram weight

The quantity of goods ordered above 1500㎡ shall be quoted according to the above specifications, and the quantity of goods ordered between 800 and 1500㎡ shall be quoted according to the specifications.2 times the performance, the order quantity of 400-800㎡ below the price of the goods according to the specification of 1.5x performance

Standard for accounting of plate making fee and freight: Flexo 0.25 yuan square centimeter, electric engraving 0.5 yuan square centimeter, die cut version 0.025 yuan square centimeter, freight calculation according to the practice of freight divided by the number of shipments, according to the commodity technology clutter, high-grade paper and other appropriate addition of processing fees。

In carton quotation calculation, the purchase price of paper is changed, the ex-factory price coefficient is not reasonable, the equipment of the carton manufacturer is how to use the width of the drum material is not matched with the width of the carton manufactured, and so on will affect the quotation of the carton。

Carton area accounting

1) The open side of the carton is divided into a single piece containing the side of four boxes and a single piece containing the side of two boxes

2) Calculation formula of carton area

Most of the materials used in the carton factory are web paper, and the usual width of web paper is 960mm, 1100mm, 1600mm and 1940mm, and can also be customized according to user needs。The width * width of the equipment of the carton factory is 2.2m, usually 1.6m。

The calculation of carton area is as follows:

第1）

Divide the width of the equipment (assuming the width of the equipment is X meters) by the width + height +0 of the carton.06m) Take an integer (suppose this integer is y), then y indicates that the width of the equipment can produce several cardboard boxes together。Therefore, when planning the carton, the width and height of the carton should be taken into account as far as possible, that is, the planner should give priority to the number of rows and layers of the contents to meet the sale count, and meet the number of paper openings, and reduce the single cost of the carton due to the small number of cuts。  The width of the valuation area of the carton is X÷Y = B, and the length of the valuation area of the carton is the length + width +0 of the carton.06）×2＋0.04 = A, that is, A is the length of the accounting area of the carton, so the area of the carton is B×A = S, that is, S is the area of the carton at the time of pricing。The quantity units of length, width and height in the formula are 0 in meters (m).06 represents that the trimming amount of the carton board in the long and wide directions is 60mm, 0.04 is the tongue edge, and these two values are values that can only be increased and cannot be reduced。

Iii. Accounting examples:

The existing customer wants to manufacture A five-layer corrugated box with an inner diameter of (500mm×310mm×240mm). It is necessary to select the face paper as 300g/high watt 180g (A/B corrugated)/core paper as 180g/inner paper as 280g tea board paper, and check the quotation of the carton。Machine equipment roll paper width is 1.6m.。

(1) The area calculation of the carton is as follows:

Width of carton: 1.6÷（0.24＋0.31＋0.06）＝2

1.6÷2＝0.8

Length of carton: (0.5＋0.31＋0.06）×2＋0.04＝1.The area of the 78m2 carton is: 1.78×0.8=1.42 m2

(2) The price of five layers of corrugated box board paper per square meter is: 7.$63 (see accounting in Section 3)

(3) The quotation for cartons is 7.63×1.42＝10.83 yuan box bulkhead, filling plate imitation method calculation。

Carton factory according to the practical needs of customers, if the demand is large, you can specially choose 1.3m paper in 1.6m machine manufacturing, then the carton price will be much lower, still calculated as follows:

（0.31＋0.24＋0.06）×2＝1.22

The carton factory can use a width of 1.3m material to make cartons。

The price width of the carton corrugated board is 1.3÷2＝0.65

The pricing length of the carton corrugated board is (0.5＋0.31＋0.06）×2＋0.04＝1.78 Area of the carton S = 1.78×0.65＝1.157 Then the quotation for the carton is 1.157×7.63＝8.83元

Carton calculation carton factory calculation basic formula different box types have different surface areas, the same box type because of the reduction of the number of carton side sides contained in a single piece and increase the price of each carton。

In carton quotation calculation, the purchase price of paper is changed, the ex-factory price coefficient is not reasonable, the equipment of the carton manufacturer is how to use the width of the drum material is not matched with the width of the carton manufactured, and so on will affect the quotation of the carton。
